ERNEST STARBUCK, OF PEORIA, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGN- MENTS, 'IO EDWARD M. SMITH, OF PEOR/IA, ILLINOIS.

RUBBING-POST.

To all whom t may concern Be it known that I, ERNEST STARBUGK, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Rubbing-Posts; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to a hog greaser or rubbing post. lt pertains particularly to a rubbing post having an elevated receptacle for oil or a disinfectant and one or more smaller auxiliary receptacles to receive and measure small quantities of the oil from said .smaller receptacles upon the rubbing part or parts.

ln certain types of hog greasers there is a movable rubbing part operated by the hog, the movement of which results in liberating the oil or disinfectant which runs down said part. As very often occurs the animal will sometimes lie against the member and thereby hold the oil exit open with the result that the oil is wasted and the rubbing post is of little use until the oil is replenished, and due to this loss the cost of the oil in time becomes considerable. In view of this, it is my purpose to provide a hog greaser in which but a small portion of the oil will be discharged each time the animal uses the post the oil being prevented, automatically, from flowing when this small portion has been discharged and when the hog lies against the rubbing part.

Therefore, an object of the invention is to provide a receptacle for holding a very small quantity of oil which receptacle has communication with and is automatically supplied from a larger receptacle, the oil in the said smaller reservoir being discharged in the rubbing movement of the animal upon the rubbing part.

Another object of the invention is to provide, in arubbing post, an elevated tank or receptacle for oil which has a smaller receptacle in communication therewith that can be alternately lilled and discharged upon the rubbing surface due to the movements of the animal.

Another object is to provide a main receptacle for oil and a 4smaller .one in connection with and to be ,supplied from it., .and a dou.-

ble valve adapted in one of its extremes of movement to permit entrance of oil to the smaller receptacle and in its other extremity to allow the discharge therefrom.

Another object is to furnish a rubbing member for a device of the nature described to operate a part for the discharge of an oil or disinfectant, said member being so mounted that the smallest as well as the largest animal may readily operate it.

Another object is to construct a rubbing post of simple form and of low cost.

The invention, besides the above, relates also to certain details of construction as will be pointed out herein assisted by the accompanying drawing in which:

Figure l is an elevation of my rubbing post, parts of which are shown in section. Fig. 2 is a plan of a portion of the same. Fig. 3 is an enlarged section of parts shown in Fig. 1. Fig. A shows a part of a valve stem in perspective. Fig. 5 shows a portion of a leg of the rubbing post in perspective. Fig. 6 shows the under side of the upper portion of the device, parts of which are shown in section, and Fig. 7 shows a rubbing member in perspective.

A is a. receptacle for the oil, preferably a casting, provided with any suitable lid B. Extending from the bottom of the receptacle is a hollow centrally disposed extension into which is screwed, driven, or otherwise secured, a standard consisting for instance of a piece of piping D.

E indicates a base preferably having three legs F and having also a socket Gr into which the lower end of said pipe D is screwed, driven, or otherwise secured.

Cast with the bottom of the receptacle A are spaced hollow extensions H, I having shown three in the present instance. The extensions are tubular and each constitutes a receptacle for oil, being Vprovided with an upper and lower wall. The upper one has an opening .l and the lower one an opening K which7 in the present instance, is much larger in diameter than the said opening J. A valve stem L lextends vertically through each receptacle and through both the openings. rlhe stem slidably fits the upper opening and it is furnished near its lower end with a series of wings M which slidably fit the opening K, there being spaces N left between the wings for the passage o the oil as vwill be more fully described later.

The stein L carries at each endY a leather valve washer O adapted to rest upon and close the openings J K. Outside of each of these is a suitable washer P followed by nuts or heads Q to hold the same in place. The upper end of the stem has a series of notches R, Fig. a, which permit the oil con- Y tained in the receptacle A to flow into the receptacle H when the valve is raised and occupies the position shown in Fig. l.. An expanding spring S carried by the stem bears at one end against the upperwall of the receptacle H and its lower end rests and bears upon the wings M. The distance between the two valve leathers O is somewhat greater than the outside measurement', of the said receptacle Hl so that the stem can have ay slight vertical motion, the .spring S constantly tending to hold the upper valve O upon its seat at the top of the said receptacle H. Y

It is clear that when the stem is in its highest position the oil will enter the reccp# tacle H as already described but cannot run out of the latter by reason of the fact that the lower valve U is then seated against the bottom opening K and the means for holding the valve in this position will be described presently. But w ien the spring 1s permitted to act the opening KA is exposed by lowering' the stem L, the lower valve O permitting the oil to run out through the openings N. It will be observed thatin broken lines in Fig. 3 the extremities of the stem L are reduced in size soas to be smaller in diameter than the body of the stem. In

this way the valves O can rest upon the resulting shoulders and can positively close the openings J K.

T is a rubbing member arranged in an upright position between the base E and receptacle A and swings on a vertical axis. To this end acast hollow boss U depends from the bottom of the receptacle A at three places as indicated in Fig. 2 and in the base E is a socket V in line with each, but one of which is shown,'see Fig. l. The upper end of the said member T is provided with a trunnion W adapted to seat in the socket of the said boss U while the lower end of the member has an adjustable trunnion 2. This has a vertical slot 3. Bolts 4; extend through the slot and a part of the member, Fig. 1. This structure permits the said trunnion 2 to be adjusted vertically as desired so that the member T can be given as free movement as desired. The trunnions W at the upper ends of the members T are stationer at one sideY of the housings H, as shown in dotted lines in Fig. 2. The said members T are broad in horizontal measurement and the trunnions W, 2, are mounted at one edge of the same so that the members will be made to swing when pressure is placed upon r, them. Extending from the upper end of each said member T, atl about the middle, is a finger 5 which face adapted to have contact with the lower end of the stem L. A spring 6 is mounted on the upper trunnion W one end bearing upon the member L the other against some fixed part of the apparatus, for instance the pant C extending from the bottom of the receptacle A. The tendency of the spring is to hold the member T outward with its finger 5 in contact with the lower end of the valve stem L, the incline of the finger 5 being such that when the member is moved outward the lower end of the stem will be positively engaged and the lower valve O will bev firmly held upon its seatrand prevent the discharge of oil from the receptacle H.

The hog in rubbing upon the member vT swings it on its axis and in consequence the finger 5 is shifted allowing the spring S to force the stem L downward and cause the upper valve O Yto seat. There is then no communication of the receptacle H with ltheY receptacle A. This movement permits the oil to pass out of the receptacle H through the opening K and it then flows down the linger 5 and upon the outer surface of the member T from which Ythe hog receives itin his rubbing movements. erts considerable force so that it will overcome and compress the spring S and overcomes what friction there may be.

has an inclined upper sur-Y The spring 6 ex-V It is observed that if the member kremains I in such a position as to allow the valve to retain its lowest position there can be no loss of oil since none can be discharged from the receptacle A until the valve is again raised at the time the member T is allowed to re-V gain its normal position at which time its inclined surface will raise lsaid valve. In assembling the rubbing post the sockets that receive the trunnions are brought in line vertically so that the members T can bc easily put in place and in putting these in position the upper trunnions are properly seated and the lower adjustable ones can then be properly adjusted in their sockets in the base E. Tt is thus seen that although the parts of the body of the device may be permanently connected the members T can be removed and replaced with ease.

It is to be stated mounting the member T may be resorted to since it is not the desire to be confined to what has been described as the mounting means. The advantage.l however, in pivotingthe member at both ends and o'setting the pivots substantially as shown, is that no 'more power is required at one point in its length than at another in order to swing it so that an animal, no matter how small, may as easily move it The members, of course, may be roughened on their outer faces. if desired and it is obthat any manner of as very large animal.V

served that I suspend the said members above the legs F so that any excess oil can fall thereon, the latter serving as receptacles which, in extending for some distance away from the members, and being comparatively low, can be used by the animal upon which to rub his under parts. The receptacle is constituted by providing ribs 7 which are raised above the edges of the legs as clearly shown. rThe surface of the leg is also roughened in any desired way for instance by providing a series of raised ribs S for the animal to rub upon and from which the oil will be taken, the ribs distributing the oil upon the affected parts of the animal in the rubbing action.

I wish to state that I am aware of a devicel that measures a disinfectant between two valves for spraying animals but the structure employed is complicated and involves considerable expense in its manufacture besides which the spraying nozzle is suspended above the place occupied by the animal in rubbing and in being thus suspended will be either too high or too low according to whether a small animal or a large'one uses the device. In one case the fluid will be Wasted in large quantities each time a small animal is treated because the nozzle is too far away, and in the other event the animal cannot get into position, because the nozzle hangs too low, and cannot receive the benefit of the fluid. It is highly important to arrange for a saving of as much of the fluid as possible in a rubbing post because of the cost. The method of providing for such saving is to measure a small quantity of the fluid each time the device is used and to effect a still further saving the fluid must be discharged directly upon a surface for the animal to rub against. To this end I have arranged the structure herein described which while measuring the fluid at an elevation high enough to permit an animal of any size to approach, also arranges for the delivery of the required small amount upon a member easily rubbed against and operated by the largest vand smallest animals alike.

My rubbing post or hog oiler is distinguished from others of its class from the fact that the rubbing member T is normally in engagement with the valve stem to hold the valves O constantly raised so that the small receptacle is kept filled with the fluid and ready to deliver a measured quantity upon pressure being` applied to the said rubbing member to withdraw it from andrelease the valve. At this time the valve seats to prevent oil being supplied from the large receptacle to the now open small one. The member T directly underhangs the valve so as to catch all of the oil upon its surface.

rI`he general form of my rubbing post or oiler is such that it can be set in any con venient or desired location where the animals may reach it from all sides.

I may make such slight changes in my device as might suggest themselves without departing from the spirit of the invention and the scope of the claims.
